An authenticated user with permission to view file-attachments may be able to move/remove arbitrary files on the server.
Upgrade Note: This update constrains access to APIv4's File entity and the recently added option, move_file. The constraint parallels a similar constraint in APIv3's Attachment. To use the move_file option, you must invoke the API through a trusted channel (e.g. PHP-API) and set checkPermissions=>FALSE.
(If you need remote access to this functionality, please create or comment on a Gitlab issue with a proposed permission model.)
